A halogenated thymidine analogue with potential antineoplastic and radiosensitizing activities. Bromodeoxyuridine competes with thymidine for incorporation into DNA, resulting in DNA mutation and the inhibition of cell proliferation. As a radiosensitizer, this agent is associated with the inhibition of repair of radiation-induced DNA double-strand breaks (DSBs). Check for active clinical trials using this agent. (NCI Thesaurus)
